Which nodal tissue is responsible for receiving impulses from the SAN and delaying them slightly before passing them to the ventricles?
Show answer and explanation
Correct answer: Atrio-ventricular node
The atrio-ventricular node (AVN) is located in the lower-left corner of the right atrium close to the atrio-ventricular septum. It picks up the impulse from the SAN, delays it briefly to allow the atria to fully contract, and then transmits it to the AV bundle (Bundle of His).
